Floral patterning in Arabidopsis requires activation of floral homeotic genes by the floral meristem identity gene, LEAFY (LFY). Here we show that precise activation of expression of class B and C homeotic genes in floral meristems is regulated by three flowering time genes, SHORT VEGETATIVE PHASE (SVP), SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1), and AGAMOUS-LIKE 24 (AGL24), through direct control of a LFY coregulator, SEPALLATA3 (SEP3). Orchestrated repression of SEP3 by SVP, AGL24, and SOC1 is mediated by recruiting two interacting chromatin regulators, TERMINAL FLOWER 2/ LIKE HETEROCHROMATIN PROTEIN 1 and SAP18, a member of SIN3 histone deacetylase complex. Our finding of coordinated regulation of SEP3 by flowering time genes reveals a hitherto unknown genetic pathway that prevents premature differentiation of floral meristems and determines the appropriate timing of floral organ patterning.
